Question

\(\dfrac{x}{-2}=\dfrac{-8}{x}\)

Answer 1

\(\dfrac{x}{-2}=-\dfrac{8}{x}\)

\(\Rightarrow x^2=16\Rightarrow x\pm4\)

Chúc bạn học tốt!!!

Answer 2

\(\dfrac{x}{-2}=\dfrac{-8}{x}\Rightarrow x\cdot x=\left(-2\right)\cdot\left(-8\right)\Rightarrow x^2=16\Rightarrow x=\pm4\)

Answer 3

- Ta có: \(\dfrac{x}{-2}\)= \(\dfrac{-8}{x}\)

<=> x * x = -2 * (-8)

<=> x² = 16

<=> x = \(\sqrt{16}\)

<=> x = 4

- Vậy x = 4 khi \(\dfrac{x}{-2}\)= \(\dfrac{-8}{x}\).

Answer 4

\(\dfrac{x}{-2}=\dfrac{-8}{x}\Rightarrow x.x=\left(-2\right)\left(-8\right)\Rightarrow x^2=16\Rightarrow x=\pm4\)

Answer 5

\(\dfrac{x}{-2}=\dfrac{-8}{x}\)

\(\Rightarrow x^2=16\)

\(\Rightarrow x=\pm4\)
